At first glance: mental state is a comprehensive reflection of nervous system function and dog health. A healthy dog should have bright eyes, flexible ears and tail, react quickly when someone approaches, and show active approach or avoidance. If your eyes are dull and depressed, you are more likely to get sick.

Second, look at the whole: observe whether the dog's movements are flexible, whether the gait is steady, whether the coat is neat and smooth, whether the muscles are plump and symmetrical, whether the limbs are symmetrical and powerful, and whether there is limping. If there are obvious scars, depilation and papules (papules) on the body surface, it indicates that the dog has or has had skin diseases (mites, demodex, dermatomycosis, etc.). ).

3. Look at the eyes: Healthy dogs have bright eyes, clean eyelashes and moist eyes. Many diseases of dogs are reflected in the eyes. Flushing of conjunctiva (inside eyelid) is a sign of some infectious diseases and fever. The yellow staining (beige) of conjunctiva indicates that the dog's liver may be diseased. The pallor of conjunctiva is mostly caused by anemia in dogs. When the cornea (the outermost layer of the eyeball) appears cloudy white spots, it may be the middle and late stage of canine distemper or simple keratitis; If the cornea is blue-gray, it is more likely to have infectious hepatitis (also known as "hepatitis blue eye" in clinic). If there is too much chewing gum, you should pay more attention. Many dogs with canine distemper and infectious hepatitis have this phenomenon.

4. Look at the nose: The nose tip and nostrils of healthy dogs should be moist and cool. If the nose is dry, it means that there is inflammation in the upper respiratory tract (mostly caused by infectious diseases and febrile diseases). For example, there is obvious serosity in the nostrils, and mucus and purulent nasal mucus are the manifestations of some infectious diseases (influenza, canine distemper, etc.). ).

5. Look at the abdomen: people who buy dogs for the first time or don't know much about dogs often ignore this. If there are obvious spherical bulges around the dog's navel and abdomen, it is mostly the result of the dog's umbilical hernia and scrotal hernia, which can generally be treated by surgery.

Matters needing attention after buying a dog:

How old is my dog?

2. Has he been vaccinated?

Is he in a normal state now?

If your dog is between 2 and 3 months old, don't give him a bath, and don't believe that the dog dealer has done "epidemic prevention", because the time is wrong, and the correct epidemic prevention process can only be completed after 15 weeks. Whether his current state is normal is mainly reflected in his mental outlook, appetite, fur, nose, mouth and eye secretions, whether he has a lot of gum, yellow nose and strange secretions in his mouth. Whether the body temperature is normal (normal body temperature: 38-39), whether the excrement is normal, whether there is diarrhea, whether the urine color is normal (if the urine color is dark, it may be poisoned), and whether there is cough, including cough induced by people pinching their necks. If anything does not meet the requirements, don't bathe or vaccinate the puppy for the time being, because the puppy is very weak after changing the environment and it is difficult to keep warm after bathing. Vaccines are mostly dead vaccines or attenuated vaccines, which means that the vaccine itself is also a virus. If the dog is vaccinated when it is sick, the vaccine will become a catalyst to accelerate the onset of the dog.

If your dog is normal in any way, I suggest you wait for a week. Sometimes there are healthy dogs with poison, that is, they are sick but have no seizures. Vaccination at this time is no different from killing him. If there is still no problem after a week, you can give him an epidemic prevention. After a week, his resistance can be improved to 10-20%. You can give him a bath at this time, but you must keep warm, but personal advice.

Few people will feed the same food as the original owner, even if they all use dog food, it will not be a brand, and dog dealers will not be willing to buy dog food to feed their puppies. So I suggest you feed your dog puppy food. If the dog is too young, you can feed the dog milk powder and add a little lactase to the milk powder to prevent him from having diarrhea after changing food. Slowly adding dog food to milk, instead of milk, will generally lead to diarrhea in puppies. In severe cases, it will cause dehydration. During this period, you can prepare some "Mi Cola" at home to prevent the puppy from having diarrhea and indigestion. Don't feed other foods, including any snacks (many foods can cause poisoning or allergies to puppies, see the top post for specific food names). The puppy will excrete 20-30 minutes after waking up and 30-40 minutes after eating. At this time, you can be prepared to avoid being caught off guard. A day should be about 18- 10 hours. It's completely normal to have body convulsions when sleeping. This is not a nervous system symptom caused by canine distemper or poisoning.

Try not to let the puppy touch other dogs until he has finished the epidemic prevention, because at this time, the antibodies in his body have not fully formed and he may be infected at any time. Many friends think that it is wrong to take a bath when the dog is dirty. The dog's skin is much more fragile than you think, so the normal bathing frequency should be once every 7- 10 day. If washed for a long time, it will cause damage to his subcutaneous hair follicles: hair loss, dandruff and redness. If the hair follicle is seriously damaged, it will cause permanent alopecia areata, so please pay attention, not to mention the bath products used by people. The PH value of human skin and dog skin is completely different.

There are also many friends who think that puppies need a lot of extra nutrition. This is a wrong idea. As long as your dog's diet is basically balanced, the dog only needs extra nutrition after surgery, pregnancy and lactation. Too much nutrition intake can cause nutritional diseases, such as: too much calcium supplementation can easily lead to too thick joints in dogs; Excessive vitamins are easy to cause poisoning; Excessive fat intake can easily lead to obesity and anal gland diseases in dogs.

Finally, talking about medication, many friends don't want to go to the hospital, so it's dangerous to give medication to their puppies at home. What people hate most is to use antibiotics no matter what disease, but dogs are allergic to many antibiotics. The most typical case is that Su Mu and Xileti are allergic to ivermectin, and many dogs are allergic to penicillin and gentamicin. Therefore, it is recommended that you do not use drugs indiscriminately at home. Of course, if it's just a simple injury, you can handle it yourself. But when cleaning the wound, you must use drugs that are less irritating to the skin, such as iodine and iodine glycerin. They are all good medicines, and there is no danger for dogs to lick them, because they can disinfect their mouths, so they are non-toxic.
